The result is a new data compression method that outperforms existing techniques, such as JPEG for images, and that could eventually be adopted for medical, scientific and video streaming applications.http://phys.org/news/2013-12-compression-method-big-data-bottleneck.html

Since 1948, when the paper that created information theory first appeared, most information-theoretic analyses of secure schemes have depended on a common assumption.http://phys.org/news/2013-08-encryption-thought.html

Today, sequencing a human genome is something that a single researcher can do in a couple of weeks for less than $10,000.http://phys.org/news/2012-07-genomic-faster-algorithm.html
Biotechnology Tue, 10 Jul 2012 12:21:58 EDTnews261141702Singapore scientists design novel genome sequencing data compression methodHitachi and Data Storage Institute (DSI), a research institute of the Agency for Science, Technology and Research (A*STAR) are devising a data compression technique to tackle the increasing volume of genome sequencing data generated by the healthcare and biomedical industry. As the volume of such data has been forecasted to double annually, the collaborators aim to develop a more efficient data storage technology that will compress genome sequencing data more effectively than existing methods. This is an extension of an earlier partnership, where Hitachi and DSI researchers discovered the pattern of typical genome data transactions that would enable current storage systems to function optimally.http://phys.org/news/2012-05-singapore-scientists-genome-sequencing-compression.html

One of the most frequently used classes of algorithms in computer science, FFTs are useful for signal processing, image processing, and data compression, among other things.http://phys.org/news/2011-02-minimizing-cores.html

Business Mon, 28 Jun 2010 17:10:01 EDTnews196963157Putting the squeeze on data(PhysOrg.com) -- Data compression is one of the fundamental research areas in computer science, letting information systems do more with less. It’s the reason the iPod nano can hold thousands of songs instead of hundreds, and it’s what keeps transmitted images from choking the Internet. If every digital file is a string of bits — zeroes and ones — then compression is a way to represent the same information with fewer bits.http://phys.org/news/2009-12-putting-the-squeeze-on-data.html
Computer Sciences Mon, 21 Dec 2009 13:40:40 EDTnews180625190Seeing things: Researchers teach computers to recognize objects(PhysOrg.com) -- If computers could recognize objects, they could automatically search through hours of video footage for a particular two-minute scene. A tourist strolling down a street in a strange city could take a cell-phone photo of an unmarked monument and immediately find out what it was. And an Internet image search on, say, "Shakespeare" would pull up pictures of Shakespeare, not pictures of Gwyneth Paltrow in the movie Shakespeare in Love. Though object recognition is one of the major research topics in computer vision, MIT researchers may have found a way to make it much more practical.http://phys.org/news/2009-10-seeing-things-researchers-teach-computers.html
Computer Sciences Tue, 13 Oct 2009 10:30:07 EDTnews174646349Program does impressive file size reductions We intuitively understand the value of being able to make things smaller without sacrificing performance. The endeavor produces smaller speakers with bigger sound and a host of portable electronic devices such as digital cameras, cell phones and computers all of which continue to get smaller yet sport lots more functionality that their predecessors. And when it comes to our computer data, being able to store more in less space without sacrificing quality is also understandably desirable. Plus reducing a file's size also lets you send it faster online.http://phys.org/news/2009-09-size-reductions.html
